I've broken my right clavicle twice. I was back riding very slowly and carefully in about a month the first time. I was I some form and wanted to keep some of it so I bought a trainer. The discomfort I remember the most was my back muscles adjusting to a less wide frame.

Lance got a pin (and back on the bike quick) and my orthopedic guy thought it carried too much risk of infection and other problems. So it just knits in a big lump. But that lump is strong! Got hit by a car on the right side a few years later and the very end (I think it's called the process) was the place it broke.

Broken ribs are far more painful...
